I'm currently at the stage when I need to infiltrate the institute. I'm talking with a Faceless Centaur near Foundry and have options to tell him where the cube is (3 different options for each stage of the investigation, shouldn't there be only the latest known location?) and also an option "I'll see what I can do". If I choose the latter and talk to him again, I now can't tell him what I actually know about the cube (those 3 options I mentioned above). Seems like a dialog bug.
